<p><code>vue-resource</code>是Vue高度集成的第三方包。</p>
<p>官网链接：</p>
<ul>
<li>文档（http相关）：<a href="https://github.com/pagekit/vue-resource/blob/master/docs/http.md">https://github.com/pagekit/vue-resource/blob/master/docs/http.md</a></li>
</ul>
<p>vue-resource 依赖于 Vue。所以，我们要按照先后顺序，导入vue.js和vue-resource.js文件。</p>
<p><strong>解释</strong>：</p>
<p><code>vue.js</code>文件向Windows对象暴露了<code>Vue</code>这个关键词；<code>vue-resource.js</code>向Vue身上挂载了<code>this.$http</code>这个属性。于是，我们可以直接写<code>this.$http.get</code>或者<code>this.$http.post</code>或者<code>this.$http.jsonp</code>来调用。</p>
<h2 id="vue-resource-发送ajax请求"><a class="header" href="#vue-resource-发送ajax请求">vue-resource 发送Ajax请求</a></h2>
<p>常见的数据请求类型包括：get、post、jsonp。下面我们分别讲一讲。</p>
<h3 id="get-请求"><a class="header" href="#get-请求">get 请求</a></h3>
<p><strong>格式举例</strong>：</p>
<pre><code class="language-javascript">this.$http.get(url)
  .then(function (result) { // 当发起get请求之后，通过 .then 来设置成功的回调函数
    console.log(result.body); // response.body就是服务器返回的成功的数据
    var result = result.body;
  }, function (err) {
    //err是异常数据
  });
</code></pre>
<p>获取到的<code>response.body</code>就是要获取的数据，但直接打印出来是 object，所以要记得转成string。</p>
<p><strong>举例</strong>：获取数据</p>

<h2 id="jsonp的实现原理"><a class="header" href="#jsonp的实现原理">JSONP的实现原理</a></h2>
<p>由于浏览器的安全性限制，默认不允许Ajax发起跨域（协议不同、域名不同、端口号不同）的请求。浏览器认为这种访问不安全。</p>
<p><strong>JSONP的实现原理</strong>：通过动态创建script标签的形式，用script标签的src属性，代表api接口的url，因为script标签不存在跨域限制，这种数据获取方式，称作JSONP（注意：根据JSONP的实现原理，知晓，JSONP只支持Get请求）。</p>
<p>具体实现过程：</p>
<ul>
<li>
<p>先在客户端定义一个回调方法，预定义对数据的操作</p>
</li>
<li>
<p>再把这个回调方法的名称，通过URL传参的形式，提交到服务器的api接口；</p>
</li>
<li>
<p>服务器api接口组织好要发送给客户端的数据，再拿着客户端传递过来的回调方法名称，拼接出一个调用这个方法的字符串，发送给客户端去解析执行；</p>
</li>
<li>
<p>客户端拿到服务器返回的字符串之后，当作Script脚本去解析执行，这样就能够拿到JSONP的数据了</p>
</li>
</ul>
<h2 id="axios"><a class="header" href="#axios">axios</a></h2>
<p>除了 vue-resource 之外，还可以使用 <code>axios</code> 的第三方包实现实现数据的请求。</p>
<h2 id="通过vue全局配置api接口的url地址"><a class="header" href="#通过vue全局配置api接口的url地址">通过Vue全局配置api接口的url地址</a></h2>
<p>api接口的url地址包括：绝对路径+相对路径。</p>
<p>我们在做Ajax请求的时候，所填写的url建议填<strong>相对路径</strong>，然后把<strong>绝对路径</strong>放在全局的位置。</p>
<p>Vue就提供了这个功能。举例如下：</p>
<pre><code class="language-html">  &lt;script&gt;
    // 如果我们通过全局配置了，请求的数据接口 根域名，则 ，在每次单独发起 http 请求的时候，请求的 url 路径，应该以相对路径开头，前面不能带 /  ，否则 不会启用根路径做拼接；
    Vue.http.options.root = 'http://smyhvae/';
    // 全局启用 emulateJSON 选项
    Vue.http.options.emulateJSON = true;

    var vm = new Vue({
      el: '#app',
      data: {
        name: '',
        list: [ // 存放所有品牌列表的数组
        ]
      },
      created() { // 当 vm 实例 的 data 和 methods 初始化完毕后，vm实例会自动执行created 这个生命周期函数
        this.getAllList()
      },
      methods: {
        getAllList() { // 获取所有的品牌列表
          // 分析：
          // 1. 由于已经导入了 Vue-resource这个包，所以 ，可以直接通过  this.$http 来发起数据请求
          // 2. 根据接口API文档，知道，获取列表的时候，应该发起一个 get 请求
          // 3. this.$http.get('url').then(function(result){})
          // 4. 当通过 then 指定回调函数之后，在回调函数中，可以拿到数据服务器返回的 result
          // 5. 先判断 result.status 是否等于0，如果等于0，就成功了，可以 把 result.message 赋值给 this.list ; 如果不等于0，可以弹框提醒，获取数据失败！

          this.$http.get('api/getprodlist').then(result =&gt; {
            // 注意： 通过 $http 获取到的数据，都在 result.body 中放着
            var result = result.body
            if (result.status === 0) {
              // 成功了
              this.list = result.message
            } else {
              // 失败了
              alert('获取数据失败！')
            }
          })
        }
      }
    });
  &lt;/script&gt;
